Open publisher page 22 citations

Abstract

The James Webb Space Telescope Optical Telescope Element (OTE) and Optical Telescope Element/Integrated Science Instrument Module (OTIS) will be tested at the same time in the final and only cryogenic optical test of the observatory. Due to the size and temperature of JWST, this is a complex test which has undergone changes in the last year aimed at reducing test execution risk. We will summarize the test plan changes, architecture changes, and predicted timeline changes for this test. We will also explain the checkout plans for assuring the test will go smoothly.
